Did you know that cracking walls and uneven floors in homes are usually symptoms of a deeper, structural problem? For homeowners, regardless of where they live, identifying structural issues early and addressing them in the right way is vital. Here’s a tip: understanding the soils beneath your home can be the key.

Retaining walls are an increasing feature of construction sites as sky high land prices add pressure to maximise the potential returns from each build.

Retaining walls are an increasing feature of construction sites as sky high land prices add pressure to maximise the potential returns from each build. Construction companies look to utilise every inch of land when planning new developments, and many projects require high retaining walls to achieve bigger results.

When Offset Developments, a residential building company based in Christchurch, began construction on a four-unit complex in Christchurch, it encountered a significant challenge when it came to laying the foundations. The water table was only 1.2m below the surface, contributing to the very soft ground conditions. After receiving a geotechnical report, the company was advised it needed to place a raft under the slab to protect the site from possible subsidence, soil liquefaction or other issues that may arise due to the weaknesses of the ground.

Ground engineering and asset preservation specialist Mainmark has successfully re-levelled two large commercial buildings in under five weeks using JOG Computer-Controlled Grouting, a non-invasive, highly precise system of grout injection. The two buildings, part of a complex in Melbourne, were remediated in a matter of weeks which is remarkable given the complexity of the project.

As construction companies look to utilise every inch of land when planning new developments, retaining walls are becoming an even more integral part of site works. Indeed, many projects are featuring increasingly high retaining walls to maximise their construction outcomes.

When it comes to public safety, businesses and building owners have a responsibility to identify and manage potential hazards at their premises. Slips, trips and falls are a common occurrence and while people stumble and fall for all sorts of reasons, it’s important to maintain floors and walkways for all visitors or employees at the site.

For the past 25 years, Sandgate Uniting Church’s annual Christmas lights display has been a part of the fabric of the northside community. But every local icon needs a little TLC at times. This year was the first time for the church’s light show and Yatala-based engineering company Mainmark stepped in the help.

Safety and productivity have always been the top drivers in just about any mining operation. Yet as facilities age and the need for return on investment grows, these two parameters often work against each other. Austmine caught up with Greg Wearing from ground engineering specialist Mainmark to discuss why innovation holds the key and must become the core business function of any mining services company.
But when is a crack something minor or a problem that needs to be tackled on a bigger scale?

Most homeowners will spot a crack or two (or more) in their house at some time, even those who don’t live in an earthquake zone.But when is a crack something minor or a problem that needs to be tackled on a bigger scale?

Mainmark: There is estimated to be approximately 50,000 abandoned mines across Australia with a significant number of these posing threats to both public safety and the environment. According to the 2012 NSW Auditor-General Report, derelict mines represent the largest category of contamination liability for the state of NSW.
